It was a wonderful experience. The crew was fun and informative. The night was cloudy but they mangrove provided the darkness needed to see the bioluminescence

Didn’t know that the tarp was used for viewing the glow it was different and difficult from the last time I came on this tour I was able to just use my hand in the water and see a glow

Bucket list
Lindi_M, Sep 2023
This was a bucket list experience! Guides Noel, Annalise, and Miguel were great! Our group was full of kayakers with different skill levels and all guides were patient and helped the group complete the tour safely. The information was fascinating and the experience itself was once in a lifetime! I highly recommend this trip-just don’t Forget your water shoes!
Response from Host, Sep 2023
Thank you so much for your fantastic review! We're thrilled to hear that your bucket list experience with guides Noel, Ineliz, and Miguel was a success. It's wonderful to know that they made sure everyone, regardless of skill level, had a safe and enjoyable time. We appreciate your recommendation, and you're absolutely right - water shoes are a good idea! We hope to welcome you back for another adventure soon. -KPR Team
Rude tour guide
Tony_M, Sep 2023
Kayaking in the dark and having other kayakers pushing you off the side makes it tough. Making it even worse, the tour guide by name of Brian was exceptionally rude. Barked at us when he stop pedaling, " why does he still hear us splash our pedals, when he stopped. On top of that, he threatened if we splash one more time we will be towed by. This is on top of yelling at us to pedal harder. Which one is it? Brian needs an attitude readjustment class. He made this experience very upsetting for us. Would not recommend for beginners. David was the complete opposite which gave encouragement to the other new kayakers. Miguel was a fun and educational guide. And Eloise was nice with the pictures. Feels bad to have one bad attitude person ruin it for the rest of us.
Response from Host, Sep 2023
Hola Tony, We are very sorry to learn the experience was less than expected. We would like to speak with you regarding this feedback.

Well run tour
Sean_P, Aug 2023
We went on the earlier tour (6:15) and liked our choice. Got to paddle to the lagoon with some daylight through the mangroves and it was great. The paddle back in darkness was fine but happy to not be in darkness both ways. The tour is well run, great guides - shared some info about the bioluminescence while in the lagoon We did a number of tours and activities while visiting. This was relaxing, interesting, and we were glad we did it

Saludos! Your positive feedback energizes us to continue delivering exceptional services. We are grateful for your recommendation and look forward to serving you again.
Need to limit your group sizes to this area
Jess_C, Aug 2023
The tour was overcrowded and resulted in an overwhelming experience. There were too many kayakers on the water, detracting from the time enjoying the bay. We spent more time navigating a cluster of kayaks coming and going from the lagoon, and connecting 15+ boats together to listen to the guide talk about the bay than actually getting to enjoy the beauty of the phytoplankton. The guides were great and talked about the area in a knowledgeable way, and I don’t think they could have done more with what they were given in terms of the amount of people on the water in their trip. This appears to be the status quo of the area, so I wouldn’t necessarily fault these guides for this experience leaving us frustrated.
Great experience at Bioluminescence Fajardo!
Zari_N, Aug 2023
We did a lot of excursions during our trip and our young adult children loved this experience the most. (age group 18-21)! Very professional staff, safe and no one left behind. Highly recommend this company.

The bio bay itself is magical. The paddle there depends on the success of the kayak in front of you.
Response from Host, Jul 2023
Hola Dan! Thank you for this review. We are glad you found it to be a magical experience! If there is anything our team can do to improve our services to make it a 5-star experience in your opinion, we'd love to hear your feedback. Your time is appreciated! -KPR Team

Easy to work with, they need to trust the weatherman
Angelina_R, Jul 2023
I never had the experience. The customer service and booking were simple. My only reason for a 3 star review is because they canceled the trip 5 minutes prior after driving an hour. There were lightning storms all day, they could have made an easy call way earlier in the day. They did issue me a refund and were very kind. I just think they should make weather decisions sooner on obvious bad weather days with terrible forecasts. I'm sure it would have been a five star adventure if we ended up going.
The bay was very poor with the blue lighting.. sky’s cloudy so the star guide was pointless. Company simply should have.
Shawn_A, Jun 2023
Should have cancelled no illuminating blue light And cloudy no stars simply just paddled out and saw a flick of blue… so disappointed
Response from Host, Jul 2023
Hola Shawn! We are sorry to read you were not pleased with the bioluminescence levels. As a natural phenomenon, we have no control over the intensity of the glow. However, when we notice the levels are low we give our guests a heads-up so each party can decide if they wish to continue with the tour. Often times guests find kayaking at night through the mangrove forest to be adventure enough. I'm sorry the experience did not meet your expectations. We hope you were able to enjoy the rest of your stay in Puerto Rico. Kind regards, KPR Team
Best adventure
Carrie_K, Jun 2023
Rated the best adventure so far by my 2 teenage kids! They loved kayaking through the red mangroves to the bay and it was beautiful to see the sparkling plankton. We had no issues at all in the trip. It felt safe and organized
Response from Host, Jun 2023
We are glad to hear that you felt safe and that your kids loved this experience. It was a pleasure and we hope to see you again.

Kate_W, Jun 2023
They refused service after trying to embarrassingly weighing my husband and they refused to refund our tour after we refused to step on the scale. We couples kayak all the time in DC with similar kayaks so we know we can ride on them without issue. We were with family and it was humiliating! This is a scam and the front desk person was incredibly demeaning and rude. Do not go!!!!
Response from Host, Jun 2023
Hola Kate, Thank you for taking a moment to express your feedback. We are sorry to hear you feel the tour is a scam. As a legitimate company, we follow strict guidelines and restrictions for safety reasons. Each company has a weight limit and it is standard practice to weigh guests to avoid putting them and the guides in unstable and unsafe situations. Keep in mind each kayak has specifications, and these kayaks may look similar, but they are not the same ones you have used. Our company actually has one of the highest weight limits allowable in the area. While we would love to have every person experience the tour, safety is our priority and we need to be realistic with the logistical limitations. These restrictions are shared in advance in multiple places to avoid this uncomfortable situation. We have no intention to humiliate anyone. With that said, we would like to hear about the interaction you had with the desk attendant. Please give us a call at (787) 245-4545 or contact us at info@kayakingpuertorico.com. We look forward to speaking with you.
No Bioluminescence, Lots of Hard Paddling
Kenya_A, Jun 2023
It was a beautiful night for kayaking. With that being said, we were told ahead of time that we wouldn’t be able to see the bioluminescence as well. I didn’t see it at all, even with the black tarp that we were told to put over our heads. It would have been a beautiful and peace tour if the guides were not rushing us. We did the tour in a much shorter time because the guides were rushing us the entire time and seemed to just want to get the tour over with. One of them actually hit me with his oar. I am not sure how an experienced kayaker accidentally did that?? I understand that you can’t control nature, and do appreciate that we were forewarned about the lack of bioluminescent visibility, but would have enjoyed it more if it were more leisurely and the guides talked more about the lagoon, the sea grass, etc.
Response from Host, Jun 2023
Hola! Thank you very much for sharing your feedback. We are really sorry that the experience you had while on the tour was not what you expected.

Good but
Allison_M, May 2023
This was a lot of fun. BUT: there were absolute beginners on this trip, at night. I don’t recommend this experience to absolute beginners. They caused chaos and frustration, for participants and the guides. Ideally folks would have paddled before or the guides would offer an experience for just beginners. The bioluminescent water was lovely. Beware, there is a strong odor outside, in the marina area of check in 🥴
Response from Host, Jun 2023

We loved the peaceful trek through the mangroves. The guide Noel was informative, engaging and super friendly. Though the plankton levels were low, we still could see it sparkle. Definitely enjoyed this experience!
